The conquerors brought with them, for their own purposes to begin with, their rigid patriarchate in the family system and their cult of Heaven (t'ien), in which the worship of sun and stars took the principal place; a religion most closely related to that of the Turkish peoples and derived from them. Some of the Shang popular deities, however, were admitted into the official Heaven-worship. Popular deities became "feudal lords" under the Heaven-god. The Shang conceptions of the soul were also admitted into the Chou religion: the human body housed two souls, the personality-soul and the life-soul. Death meant the separation of the souls from the body, the life-soul also slowly dying. The personality-soul, however, could move about freely and lived as long as there were people who remembered it and kept it from hunger by means of sacrifices. The Chou systematized this idea and made it into the ancestor-worship that has endured down to the present time.

The Chou officially abolished human sacrifices, especially since, as former pastoralists, they knew of better means of employing prisoners of war than did the more agrarian Shang. The Chou used Shang and other slaves as domestic servants for their numerous nobility, and Shang serfs as farm labourers on their estates. They seem to have regarded the land under their control as "state land" and all farmers as "serfs". A slave, here, must be defined as an individual, a piece of property, who was excluded from membership in human society but, in later legal texts, was included under domestic animals and immobile property, while serfs as a class depended upon another class and had certain rights, at least the right to work on the land. They could change their masters if the land changed its master, but they could not legally be sold individually. Thus, the following, still rather hypothetical, picture of the land system of the early Chou time emerges: around the walled towns of the feudal lords and sub-lords, always in the plains, was "state land" which produced millet and more and more wheat. Cultivation was still largely "shifting", so that the serfs in groups cultivated more or less standardized plots for a year or more and then shifted to other plots. During the growing season they lived in huts on the fields; during the winter in the towns in adobe houses. In this manner the yearly life cycle was divided into two different periods. The produce of the serfs supplied the lords, their dependants and the farmers themselves. Whenever the lord found it necessary, the serfs had to perform also other services for the lord. Farther away from the towns were the villages of the "natives", nominally also subjects of the lord. In most parts of eastern China, these, too, were agriculturists. They acknowledged their dependence by sending "gifts" to the lord in the town. Later these gifts became institutionalized and turned into a form of tax. The lord's serfs, on the other hand, tended to settle near the fields in villages of their own because, with growing urban population, the distances from the town to many of the fields became too great. It was also at this time of new settlements that a more intensive cultivation with a fallow system began. At latest from the sixth century B.C. on, the distinctions between both land systems became unclear; and the pure serf-cultivation, called by the old texts the "well-field system" because eight cultivating families used one common well, disappeared in practice.

The actual structure of early Chou administration is difficult to ascertain. The "Duke of Chou", brother of the first ruler, Wu Wang, later regent during the minority of Wu Wang's son, and certainly one of the most influential persons of this time, was the alleged creator of the book _Chou-li_ which contains a detailed table of the bureaucracy of the country. However, we know now from inscriptions that the bureaucracy at the beginning of the Chou period was not much more developed than in late Shang time. The _Chou-li_ gave an ideal picture of a bureaucratic state, probably abstracted from actual conditions in feudal states several centuries later.

The Chou capital, at Sian, was a twin city. In one part lived the master-race of the Chou with the imperial court, in the other the subjugated population. At the same time, as previously mentioned, the Chou built a second capital, Loyang, in the present province of Honan. Loyang was just in the middle of the new state, and for the purposes of Heaven-worship it was regarded as the centre of the universe, where it was essential that the emperor should reside. Loyang was another twin city: in one part were the rulers' administrative buildings, in the other the transferred population of the Shang capital, probably artisans for the most part. The valuable artisans seem all to have been taken over from the Shang, for the bronze vessels of the early Chou age are virtually identical with those of the Shang age. The shapes of the houses also remained unaltered, and probably also the clothing, though the Chou brought with them the novelties of felt and woollen fabrics, old possessions of their earlier period. The only fundamental material change was in the form of the graves: in the Shang age house-like tombs were built underground; now great tumuli were constructed in the fashion preferred by all steppe peoples.

One professional class was severely hit by the changed circumstances--the Shang priesthood. The Chou had no priests. As with all the races of the steppes, the head of the family himself performed the religious rites. Beyond this there were only shamans for certain purposes of magic. And very soon Heaven-worship was combined with the family system, the ruler being declared to be the Son of Heaven; the mutual relations within the family were thus extended to the religious relations with the deity. If, however, the god of Heaven is the father of the ruler, the ruler as his son himself offers sacrifice, and so the priest becomes superfluous. Thus the priests became "unemployed". Some of them changed their profession. They were the only people who could read and write, and as an administrative system was necessary they obtained employment as scribes. Others withdrew to their villages and became village priests. They organized the religious festivals in the village, carried out the ceremonies connected with family events, and even conducted the exorcism of evil spirits with shamanistic dances; they took charge, in short, of everything connected with customary observances and morality. The Chou lords were great respecters of propriety. The Shang culture had, indeed, been a high one with an ancient and highly developed moral system, and the Chou as rough conquerors must have been impressed by the ancient forms and tried to imitate them. In addition, they had in their religion of Heaven a conception of the existence of mutual relations between Heaven and Earth: all that went on in the skies had an influence on earth, and vice versa. Thus, if any ceremony was "wrongly" performed, it had an evil effect on Heaven--there would be no rain, or the cold weather would arrive too soon, or some such misfortune would come. It was therefore of great importance that everything should be done "correctly". Hence the Chou rulers were glad to call in the old priests as performers of ceremonies and teachers of morality similar to the ancient Indian rulers who needed the Brahmans for the correct performance of all rites. There thus came into existence in the early Chou empire a new social group, later called "scholars", men who were not regarded as belonging to the lower class represented by the subjugated population but were not included in the nobility; men who were not productively employed but belonged to a sort of independent profession. They became of very great importance in later centuries.

In the first centuries of the Chou dynasty the ruling house steadily lost power. Some of the emperors proved weak, or were killed at war; above all, the empire was too big and its administration too slow-moving. The feudal lords and nobles were occupied with their own problems in securing the submission of the surrounding villages to their garrisons and in governing them; they soon paid little attention to the distant central authority. In addition to this, the situation at the centre of the empire was more difficult than that of its feudal states farther east. The settlements around the garrisons in the east were inhabited by agrarian tribes, but the subjugated population around the centre at Sian was made up of nomadic tribes of Turks and Mongols together with semi-nomadic Tibetans. Sian lies in the valley of the river Wei; the riverside country certainly belonged, though perhaps only insecurely, to the Shang empire and was specially well adapted to agriculture; but its periphery--mountains in the south, steppes in the north--was inhabited (until a late period, to some extent to the present day) by nomads, who had also been subjugated by the Chou. The Chou themselves were by no means strong, as they had been only a small tribe and their strength had depended on auxiliary tribes, which had now spread over the country as the new nobility and lived far from the Chou. The Chou emperors had thus to hold in check the subjugated but warlike tribes of Turks and Mongols who lived quite close to their capital. In the first centuries of the dynasty they were more or less successful, for the feudal lords still sent auxiliary forces. In time, however, these became fewer and fewer, because the feudal lords pursued their own policy; and the Chou were compelled to fight their own battles against tribes that continually rose against them, raiding and pillaging their towns. Campaigns abroad also fell mainly on the shoulders of the Chou, as their capital lay near the frontier.

It must not be simply assumed, as is often done by the Chinese and some of the European historians, that the Turkish and Mongolian tribes were so savage or so pugnacious that they continually waged war just for the love of it. The problem is much deeper, and to fail to recognize this is to fail to understand Chinese history down to the Middle Ages. The conquering Chou established their garrisons everywhere, and these garrisons were surrounded by the quarters of artisans and by the villages of peasants, a process that ate into the pasturage of the Turkish and Mongolian nomads. These nomads, as already mentioned, pursued agriculture themselves on a small scale, but it occurred to them that they could get farm produce much more easily by barter or by raiding. Accordingly they gradually gave up cultivation and became pure nomads, procuring the needed farm produce from their neighbours. This abandonment of agriculture brought them into a precarious situation: if for any reason the Chinese stopped supplying or demanded excessive barter payment, the nomads had to go hungry. They were then virtually driven to get what they needed by raiding. Thus there developed a mutual reaction that lasted for centuries. Some of the nomadic tribes living between garrisons withdrew, to escape from the growing pressure, mainly into the province of Shansi, where the influence of the Chou was weak and they were not numerous; some of the nomad chiefs lost their lives in battle, and some learned from the Chou lords and turned themselves into petty rulers. A number of "marginal" states began to develop; some of them even built their own cities. This process of transformation of agro-nomadic tribes into "warrior-nomadic" tribes continued over many centuries and came to an end in the third or second century B.C.

The result of the three centuries that had passed was a symbiosis between the urban aristocrats and the country-people. The rulers of the towns took over from the general population almost the whole vocabulary of the language which from now on we may call "Chinese". They naturally took over elements of the material civilization. The subjugated population had, meanwhile, to adjust itself to its lords. In the organism that thus developed, with its unified economic system, the conquerors became an aristocratic ruling class, and the subjugated population became a lower class, with varied elements but mainly a peasantry. From now on we may call this society "Chinese"; it has endured to the middle of the twentieth century. Most later essential societal changes are the result of internal development and not of aggression from without.
